I hope that this is the death knell for conservative talk radio. It's a new world, and there is no room in it for these two hate meisters.
If you mean "heads of the Republican party" as in TALKING heads, I agree. But these two bozos are in no way the "heads" of the Republican party in the sense of any real leadership roles. They provide outlets for Republicans to reach a target audience, but I seriously doubt that either Hannity or Limburger significantly influence the direction of any GOP policy or legislative actions.
As for conservative talk radio, I doubt that it will completely go away in the short term. But I do suspect it has been overcome by events - just like all other forms of media become "old hat." It was created to provide an outlet - WHERE NONE HAD EXISTED BEFORE - for conservatives to vent about the injustice (real and perceived) heaped upon them by their government,the liberal media, and the left in general.
Now we have social media - twitter, facebook, sites like this, and all the rest - where people can interact in real time and can more or less steer their own discussion, rather than having some radio/tv "meistro" taking the conversation the way THEY (the meistro) want it to go. Once social media took hold in a widespread faashion on computers and then smart phones, THAT probably sounded the death knell for talk radio more than any recent actions like the ones cited in the basic blog post.
As to hate meisters/mongers, I'd like to see them ALL go away. Not only these two, but also the Al Sharptons, Rachel Maddows, et. al. on the left whose race-baiting and rabble-rousing add nothing to the national discussion on anything. For all of these people, it's about the ratings and about generating controversy.
That motivation undermines honest dialogue and real problem-solving. In fact, it exacerbates the problems.
I think I saw or heard somewhere that some measure of fostering bi-partisanship is in the works. I haven't researched it yet, but some of the initial moves are as simple as having Democrats and Republicans sit next to one another rather than group up in a segregated partisan manner as they do now. It sounds almost grade schoolish, but it may be a start to defuse partisan animosity between the two parties that has produced gridlock.
I know, I would be amenable to 'standing down' and lowering my verbal bombs if the other side did the same.
